EUBULUS. O71 
punctate, the interstices 3, 5, 7, and 9 sharply costate. Beneath closely punctate. Legs rather slender ; 
femora unidentate ; tibise almost straight, angulate at the base externally. 
Length 34, breadth 2 millim. (<.) 
Hab. Panama, Bugaba (Champion). 
One specimen. This insect, at first sight, appears to be nothing more than a small 
example of /. nigrodiscus; it differs, however, in the following particulars: the 
antenne are inserted much nearer the tip of the rostrum, the sides of the prothorax 
are almost parallel behind, the legs are more slender, the tarsi are less hairy, the walls 
of the mesosternum are not raised anteriorly, and the first and fifth ventral segments 
(of the male) want the long fulvous hairs. 
53. Hubulus melanodiscus, sp.n. (Tab. XXVIII. figg. 9, 9a, 2.) 
Subrhomboidal, nigro-piceous, the antenne and the tips of the tarsi ferruginous; thickly clothed with fulvo- 
cinereous scales, with a few whitish scales intermixed, the prothorax with a very large, transverse, 
rounded, velvety-black patch on the disc, the setiform scales on the elytra very short and inconspicuous. 
Head rugulosely punctate, the eyes large, coarsely facetted, and subcontiguous ; rostrum very stout, curved, 
not quite reaching the metasternum, densely, rugosely punctate and finely carinate, the apical half finely 
punctate in the 9, the antenna inserted at (¢) or at a little behind ( 2) the middle, joints 1 and 2 of 
the funiculus subequal in length, the club ovate. Prothorax short, rapidly, arcuately narrowing from the 
base, feebly constricted in front; densely, finely punctate. Scutellam rounded. LElytra wider than 
the prothorax, rapidly narrowing from a little below the base, transversely convex ; seriate-punctate, the 
interstices punctulate, 3,5, 7, and 9 sharply costate. Beneath closely punctate. Mesosternum broad, 
horseshoe-shaped. Legs rather short; femora unidentate ; tibie almost straight, angulate at the base 
externally. 
Length 33-4, breadth 2-33 millim. (¢ @.) 
Hab. Guaremata, Las Mercedes (Champion: 2); Panama, Volcan de Chiriqui 
(Champion: 3 9). 
Four specimens. Very like Z. atrodiscus, but with larger, subcontiguous eyes, the 
rostrum shorter, the antenne inserted nearer the base, the legs less clongate, &c. 
The general facies is that of a Cionus. 
54. Eubulus quadricollis, sp.n. (Tab. XXVIII. figg. 10, 10 a.) 
Oblong, shining, rufo-piceous, the femora and tibiw darker, the prothorax with a broad black patch on the 
disc, the antenne ferruginous ; somewhat thickly clothed with small fulvous scales, those on the prothorax 
coarser, the scales on the flanks of the latter and at the base of the anterior femora paler ; the prothorax 
with a broad black space down the middle, which is abruptly narrowed anteriorly, and with five fascicles 
of coarse, erect sete placed transversely across the centre and two at the apex, the seta on the disc black, 
those at the sides fulvous; the elytra with scattered, short, coarse, erect, setiform scales along each of the 
alternate interstices, the small scales condensed into a faint oblique fascia before the middle ; the legs 
setulose. Head rugulosely punctate, transversely depressed at some distance above the eyes, which are 
moderately distant; rostrum curved, reaching the metasternum, slightly widened towards the base, 
rugulosely punctate and carinate in its basal half, and minutely punctate thence to the apex, the antennie 
inserted at about the middle, joint 2 of the funiculus shorter than 1, the club oblong-ovate, compact. Pro- 
thorax broad, transversely quadrate, very abruptly narrowed in front, flattened on the disc ; densely, finely 
punctate, and feebly carinate, the two clusters of sete on each side of the black patch arising from small 
prominences. Scutellum oval. Elytra wider than the prothorax, oblong-subtriangular, the humeri rather
